COLUMBUS PHILLIPS, OF MERIDIAN, MISSISSIPYI, ASSIGNOR OF ONE-HALF TO WILLIAM D. THOMPSON, 015 DETROIT, MICHIGAN.

GAR-ROOF.

o (ZZZ whom it may concern:

Be it known that I, OoLUMnns Pmnmrs, a citizen of the United States of America, residing at Meridian, in the county of Lauderdale and State of Mississippi, have invented certain new and useful improvements in Car-Roofs, of which the following is a specification, reference being had therein to the accompanying drawings. a

The invention relates particularly to freight car roofs, and has for its object the production of a roof of this character formed solely oi metallic plates extending from save to cave of the car and supported upon the sides thereof, the plates belng of sul'licient rigidityto form cross connections between the car sides, thus eliminating the use of carlines and purlins forming the usual substructure.

The invention consists in the novel con; struction of a freight car roof of this particular type, in the peculiar arrangement and combination of its parts, and in various details of construction, as will be more fully hereinafter set forth and claimed.

In the drawings,-Figure l is a sectional perspective view of a car roof embodying my invention; and Fig. 2 is a side elevation of the roof structure.

In the drawings thus briefly described, A and B represent the car sides, C the usual side plates at the upper edges thereof, and D the end lates.

The roofing E is composed of a series of transversely extending metallic plates, as

, F, projecting from side to side of the car and 4 extending beyond each side plate as shown,

these plates being formed prefer-a ly of steel and of a tensile strength sufficient to properly connect or tie the car sides, performing the function of the usual substructure. The marginal portion of each plate is formed with a pair of flanges a and 6 extending in relation to each other and to the web or body of the plate in such manner as to form a jaw, and the jaws of adjoining plates are adapted to interlock, as plainly shown in Specification of Letters Patent.

Serial No. 566,408.

Fig. 2, forming a tie between the plate sec ably made by a series of angle plates, G,

upon each side of the ear, arranged one for each metallic sheet, and secured to. the car side beneath its cave flange, as shown in Fig. 2. ,The laterally projecting section H of the angle'clip may be, b0 ted to the cave portion of its roof plate, as shown: l

As thus constrflc ted, it will be readily apparent that the interlockingcplates constitute the roofing, and at the same time the proper connection between the car sides, whereby the usual substructure heretofore employed is entirely dispensed with and the 5 cost of production decreased accordingly. What I claim as my invention is,--

I 1. A car, having its roof formed solely of adjoining metallic platesextending from eave to cave of the car and connecting the sides, said plates having upper and lower flanges formed integral with their adjoining marginal portions, the lower flange of one plate loosely interlocking between the flanges of the adjoining plate, and the u per flange of the first plate overlapping t to uppcrflange'of the second plate forming a flexible weatherproofi joint.

2. A car having its roof formed wholly of adjoining metallic plates, said plates having upper and lower flanges formed integral with their adjoining marginal portions, the

lower flange of one plate loosely interlocking between the flanges of the adjoining plates, and the upper flange of the first late overlapping the flange of the second p ate, forming a flexible Weatherproof 'oint.

3. A car roof formed of a plurality of self sustaining load supporting plates, the marginal portions of said plates interlocking to form a weather proof joint permitting 4 xiii v I 1,096,944
